REN's human capital management is aimed at ensuring the necessary skills for complying with its mission and the development and enhancement of people.
REN also invests in the preservation of an environment of labour stability based on dialogue with employees. Due to the role that REN plays in the energy sector, particularly in terms of competence in fulfilling its mission and the quality of the public utility services that it provides, it continues to be highly attractive in the labour market.

REN includes in its activities various aspects relating to safety include the implementation of measures conducive to the prevention of potential foreseeable accidents, minimising inherent risks and mitigating the consequences of those that result from them, by applying the best safety practices in force in the energy transmission sector.
These best practices include:
- Audits, checks and monitoring of working conditions;
- Production of key internal documents to ensure compliance with safety requirements;
- Training courses at work sites for specific activities, as well as additional training in such activities as first aid, basic life support and fire prevention;
- Provision of individual protection equipment suitable for each activity;
- Inspection and coordination of safety at work that cumulatively ensures proper use of individual and collective protection equipment;
- Organisation of drills and exercises.
REN invests in the training of all employees (including subcontracted workers) involved in the construction of lines, substations, gas pipelines, stations and other energy transmission system facilities that may put workers at risk, with a view to minimising the occurrence of accidents. In the case of the conservation of the RNT and RNTIAT infrastructures, all service providers undergo prior safety-related training and awareness courses.

An event which, since 2007, joins and presents service providers with the best safety performance in the construction works of lines and substations of the National Electricity Transport Network (RNT).
The purpose of this action passes through the dissemination and awareness of good practices in the management and coordination of safety at work and the annual allocation of prizes and citations of merit in performance contracts of works of lines and substations.
As a way to distinguish and to encourage performance improvement of safety and health at work, were instituted merit awards and honorable mentions on the safety management in construction of lines and substations, which are annually awarded to the companies.
The assignment of these awards takes place in a safety technical session, organised annually by REN, to which are invited employees, performers and supervisory entities entities, allowing, thus, join the parties directly involved in the construction process and address issues related to safety at work.
Receive the merit awards entities performers with more hours worked ( in the works of lines and substation works), since I have not had any fatal accident, or another which is the result permanent disability, and have met the annual goals set by REN for the frequency and severity of accidents. Receive honorable mention other companies which meet these requirements, provided they have registered more than 40,000 hours worked in the year that reports the award. These indices, by ambitious nature that were established in 2007, remained constant to the present day.
With regard to the year 2014, in substations, the award was presented to EFACEC, with honorable mentions to the Somague Engenharia S.A., HCI Building, SA, and Engineering, SA-Conduril.
The session security techniques are so as a preferred means of ensuring the sharing of security information, enabling a knowledge extended to all parties involved about the type of accidents that occur and the causes identified, in addition to the occurrences of statistically treated security based on information collected for the whole of the works. In this way it has been possible to achieve a greater awareness and focusing the attention of the most critical aspects of security taking into account the specificities involved in infrastructure construction activities of RNT.
In addition the sessions have allowed serve security goals intended by the REN, and induced changes in some of the practices that are followed in the work. Are examples, the required reinforcement in security teams and their involvement in work, strengthening of blood alcohol controls, new requirements in terms of the contents of awareness-raising in particular given to foreign workers, regular activities of specialized security inspections, and also a greater demand on the requirements of training of the various professionals involved.
Natural Gas Perspective
The safety of the REN group natural gas infrastructure is ensured through active procedures and measures which seek to minimize the probability of incident occurrence, bringing it down to acceptable levels. Moreover, passive procedures and measures allow the impact of any actual incident to be reduced. Compliance with technical standards and national and Community legislation is a minimum requirement. It should also be noted that REN exceeds this requirement by permanently applying the best international practices in line with sector developments.
Examples of active procedures and/or devices include:
• In the case of the high-pressure NG transmission network, the implementation of restrictions of use in the field within the entire easement route and in-line inspections by smart tools as part of the management programme on infrastructure integrity.
• With regard to the Carriço underground storage, the adoption of the minimum safety distance between the outside walls of the different cavities and monitoring of soil subsidence.
• At the Sines LNG terminal, the safety control system, which is independent of other monitoring and process control systems, automatic start up of facility protection actions after certain pre-established events take place and the permanent availability of a technician responsible for the facility who is capable of dealing with unforeseen operating conditions.
Examples of passive procedures and/or measures include
• In the case of the high-pressure NG transmission network, the isolation valves in the main gas pipeline which can be activated from the Dispatch Centre and allow sections of pipeline to be isolated if required and the triggering of safety and emergency plans in the event of an incident;
• With regard to the Carriço underground storage, the activation of the below surface safety valves (SSSV) in pipes connecting the tops of the cavities to the surface and the triggering of safety and emergency plans in the event of an incident;
• At the Sines LNG terminal, the existence of retention bays to contain LNG spillages;
• At both the Carriço underground storage facility and the Sines LNG terminal, triggering of the Safety Management and Serious Accident Prevention System (Decree Law No 254/2007 of 12 July 2007).
In addition to compliance with legal and regulation requirements, more demanding complementary measures have been implemented. Of note are the drawing up of risk analyses and risk mitigation procedures as well as monitoring of activities where moderate to high risk is involved.

One of the most distinctive features of the National Transmission Network infrastructure is its extensive geographical coverage. This feature makes it naturally more susceptible to weather and environmental phenomena and break ins.
With regard to very high voltage overhead lines, it is weather and environmental factors which have greatest impact. It should be noted that more than 80% of network incidents originate in lines and the 4 most frequent causes are atmospheric discharges, forest fires, pollution related haze and birds.
Impacts on sub-stations are more localized and in principle, easier to control.
Incidents result either from equipment failures which jeopardize people and facilities or (with greater impact on safety) as a result of break ins.
Of particular concern are intruders seeking to steal valuable metals (copper, iron, aluminium, etc.). This type of vandalism is also taking place outside sub-stations and recent months have seen a growing number of thefts of iron parts used for line support.
Infrastructure surveillance for the integrity and continuity of service, including repair in the event of incident, is carried out in the System Manager Control Rooms and particularly by the Network Operation Department which uses SCADA and other tools to supervise facilities. These tools provide remote access to chronological records as well as facility status and alarms. When necessary, intervention by service teams from the Operations Department is requested.
With regard to attempted facility break in, REN has installed video surveillance systems which are complemented by intruder detection systems. These systems, which are centrally operated and supervised from the Surveillance and Service Centre in Vermoim, allow early detection of intrusion attempts. Authorities are immediately alerted to ensure fast and efficient intervention.
These systems have a dissuasive effect which we believe has helped reduce the number of break ins and thefts from facilities.
